Energy, Resources & Infrastructure

Specialists advising on the market’s most significant deals

Energy, resources and infrastructure projects are key pillars of economic growth the world over. The impacts of globalisation mean there’s never been a greater need to deliver projects more efficiently and with less risk.

Clients seek out our assistance to manage complex projects, understand regulatory requirements, fund growth, negotiate deals and navigate investment regimes. Working with us means you can access the expertise of corporate, finance and specialist lawyers from our Australian and international networks.

With each sector experiencing its own competitive tensions, regulatory scrutiny and a renewed focus on sustainable development, clients come to our practice for wide-ranging advice on energy, resources and infrastructure law. Our expertise can help you maximise sale prices, bring multinational investors to the table and develop novel structures for the most complex of projects.

Mining giants, infrastructure proponents, oil and gas pioneers, power providers and renewables innovators lean on the Mallesons team to support their leap into Australia.

The nation's most significant projects benefit from our advice, including the world’s first coal seam gas (CSG) to liquefied natural gas (LNG) project, the first Tesla Megapack big battery technology in Australia and the first sustainability-linked infrastructure financing with an interest rate directly linked to an emissions target.

We pride ourselves on having the bench strength to execute nationally significant ‘megadeals’, like the mining industry’s biggest ever deal (the Glencore/Xstrata merger) and the winning bid to acquire a majority stake in Sydney’s WestConnex – the largest road infrastructure project in Australia.

Our experience includes supporting the Port of Melbourne's world-leading multi-commodity port, Australia’s largest solar farm (Western Downs) and leading Queensland's largest class action for Seqwater.

A powerful reputation

We bring a breadth of perspective that comes from advising a range of proponents across the energy, resources and infrastructure sectors. We advise across the project lifecycle and have a powerful reputation for both understanding the issues and delivering effective solutions.
